Recovered digital data line.
A full-duplex (receiver/transmitter) asynchronous serial interface.
Interface used by the microcontroller to communicate modules and ICs.
An electrically transmitted electromagnetic wave.
See software potentiometer.
Computer programs, procedures, rules, documentation, and data
pertaining to the operation of a system.
A computer-adjustable electronic attenuator.
Frequency range within which radiation has specific characteristics.
See Serial Peripheral Interface.
Muting of audio circuits when received signal levels fall below a pre-
determined value. With carrier squelch, all channel activity that exceeds
the radio's preset squelch level can be heard.
See static RAM.
An operating mode in which the radio is muted but still continues to
monitor data.
A type of memory used for volatile, program/data memory that does not
need to be refreshed.
A timer that limits the length of a transmission.
See time-out timer.
Transmitter-receiver. A device that both transmits and receives analog
or digital signals. Also abbreviated as XCVR.
Electronic equipment that generates and amplifies an RF carrier signal,
modulates the signal, and then radiates it into space.
Transmit.
